Changed the oil and fuel filters on the Anthem yesterday. Today was the generator. I kept saying all along how easy and accessible everything was until changing out the fuel filter on the gen today. According to the manual, this was to be done via the same access door on the side for the oil filter. Was not happy with that route. It took alot of time. Has anyone done this themselves and maybe I missed something to make it easier? Ron.

I had a 7500 Onan on the TS and changing the fuel filter on that one wasn't easy either. I found tying a rag around the line wrench really helped with the fuel running everywhere. I am sure there will be a trick once I get into the Anthem.

Chuck, LA-Z-BOY suggested to me the possiblity of adding a in-line filter off the back side of the generator. He said he did that on his TS and it made things much easier and gave double protection. I asked him for some pictures next time he is under there. Ron.

Assuming it is a 10K or 12.5 k If you remove both mounting screws for the bracket that holds the filter (bolts from outside the case) you can then lift the filter and bracket out through the side panel door. Do the wrenching on the filter outside then replace. Be sure not to kink a line when you put it back inside. I drilled a new hole for one of the bolts to make it easier to get in and out.

I hope someone at Onan has not decided to save $1 by making the lines shorter...but it works like that on my '06 10k real easily.

TWOMED, The set-up may be a little different I don't know. I have a 2013 with a 12.5k. Maybe the 2006 10k is different or has different access, not sure. I should have taken a picture before I posted. I had to use a 20 inch swivel socket wrench to get to both mounting screws that hold the filter on the bracket. After that, the funnest part was trying to maneuver the filter out of the side door, and the same problem trying to get the new one back in. Ron.

Ron, The 12.5 KW sound much harder than the TS filter was. Glad it is not changed that often. I think I only replaced one, maybe two in 10 years on the TS. When is the change period, 300 hours? My oil filter was an STP 2808 from AutoZone and NAPA air filters as was the fuel filter. I don't know what the 12.5 will be yet.

Two 10mm bolts from the outside of the case release the whole bracket then you lift out filter, bracket and all.

Hope they didn't change it because it was real easy.

I think Twomed is refering to these bolts in this picture.....

Dave, thanks for posting that. That is the same setup as the 7500 was. On the 7500 only the center bolt needed to be removed. It doesn't look like the access is as easy on the 12.5 though.

Dave,Another lesson learned. But that's one of the benefits of this forum. After removing the filter mounting nut, I was snaking the darn thing out the back and around the inside of the bracket. Better luck next time.Ron.
